The Nawab of Dhaka, originally spelt in English Nawab of Dacca, was the title of the head of one of the largest Muslim zamindar in British Bengal and Assam, based in present-day Dhaka, Bangladesh. The title of nawab, similar to the British peerage, was conferred upon the head of the family by Queen Victoria as a recognition of the first Nawab's loyalty and contribution to the social welfare activities.

Nawab, also spelled Nawaab, Navaab, Navab, Nowab, Nabob, Nawaabshah, Nawabshah or Nobab, is a royal title indicating a sovereign ruler, often of a South Asian state, in many ways comparable to the western title of Prince. The relationship of a Nawab to the Emperor of India has been compared to that of the Kings of Saxony to the German Emperor. In earlier times the title was ratified and bestowed by the reigning Mughal emperor to semi-autonomous Muslim rulers of subdivisions or princely states in the Indian subcontinent loyal to the Mughal Empire, for example the Nawabs of Bengal.
